Understanding Shadows
Shadows are formed when an object blocks light from a light source. To make a shadow disappear, we can manipulate the position of the object or the light source. Here are the ways to make a shadow disappear and why option 'D' is not effective.
Option A: Move the Object Closer to the Light Source
- When the object is moved closer to the light source, the shadow becomes smaller and may even disappear if positioned perfectly.
Option B: Move the Object Farther Away from the Light Source
- Moving the object farther away from the light source can also reduce the size of the shadow. However, it can also make the shadow larger if the distance increases too much.
Option C: Turn Off the Light Source
- Turning off the light source eliminates the light that creates the shadow, making it disappear completely.
Option D: Shine a Second Flashlight on the Object
- This option does not eliminate the shadow but rather creates a new one. When a second flashlight is added, it can create multiple shadows or enhance the existing one, depending on the angles of the lights. Therefore, shining a second flashlight does not make the original shadow disappear.
Conclusion
To effectively make a shadow disappear, one must either change the position of the object relative to the light source or remove the light source itself. Option 'D' does not achieve this goal, making it the correct choice as the method that does not make a shadow disappear.

Shining a second flashlight on the object will not make the shadow disappear. It may create an additional shadow but won't eliminate the first one.
